Koss KE5 In-ear Headphones, Black/White

The Koss KE5 are wired in-ear headphones designed for portability and daily audio playback. Their contoured frame is intended to provide a secure and stable fit for extended listening sessions. Audio is reproduced across a frequency response range of 60 Hz to 20,000 Hz. Connection is established via a standard 3.5 mm audio plug, ensuring compatibility with a wide range of devices that include a traditional headphone jack, such as laptops, portable media players, and select smartphones.

These earbuds present an impedance of 16 ohms and a sensitivity of 96 dB, making them easy to drive with most consumer-level audio sources without requiring an external amplifier. The attached cable has a fixed length of 1.2 meters, which provides sufficient slack for connecting to a device in a pocket or bag. Weighing 27 grams, the construction is lightweight for on-the-go use. This model does not integrate a microphone for voice calls or feature any form of active noise cancellation, focusing entirely on audio output.
